# ecmwflibs
## Compiling on a Mac
### Creating the macos version of the package
First make sure you have the required packages:
```bash
brew install python3
brew install cmake
brew install pango cairo proj pkg-config
brew install netcdf ninja
pip3 install delocate wheel
```
This can be achieved by simply typing:
```bash
make tools
```
Then:
```bash
cd ~/git/ecmwflibs
make clean
make
twine upload wheelhouse/*
```
### To select an earlier version of Python, use pyenv:
```bash
brew install pyenv
brew install pyenv-virtualenv
pyenv install 3.6.5
pyenv virtualenv 3.6.5 py36
pyenv activate py36
pip3 install ninja delocate wheel
cd ~/git/ecmwflibs
make clean
make
twine upload wheelhouse/*
```
### Creating the linux version of the package
Cross compiling a Linux version on a Mac requires Docker installed.
```bash
cd ~/git/ecmwflibs
make image
make clean
./dockcross-build-ecmwflibs make
twine upload wheelhouse/*
```
You can also compile interactivaly
```bash
./dockcross-build-ecmwflibs bash
make
exit
```
### Creating *all* linux versions of the package
```bash
cd ~/git/ecmwflibs
make image
make clean
./dockcross-build-ecmwflibs make wheels.linux
twine upload wheelhouse/*
```
## Compiling on Linux
Not tried, but the docker-based solution should work.
